performs a DNS lookup to find the correct IP address.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process typically involves several steps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the browser checks local cache<\/li>\n\n\n\n<li>the operating system checks cached DNS records<\/li>\n\n\n\n<li>a recursive DNS resolver is queried<\/li>\n\n\n\n<li>the request is passed through DNS servers until the correct record is found<\/li>\n\n\n\n<li>the final IP address is returned to the browser<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This process happens automatically and usually takes only a fraction of a second.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"DNS_structure\"><\/span>DNS structure<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">DNS is organized in a hierarchical structure:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Root DNS servers<\/li>\n\n\n\n<li>TLD (Top-Level Domain) servers such as <code>.com<\/code>, <code>.pl<\/code>, <code>.net<\/code><\/li>\n\n\n\n<li>Authoritative DNS servers that contain actual domain records<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Each level helps direct the request closer to the final destination.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"DNS_records\"><\/span>DNS records<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">DNS information is stored in records, which define how a domain behaves. Common record types include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A record \u2013 maps a domain to an IPv4 address<\/li>\n\n\n\n<li>AAAA record \u2013 maps a domain to an IPv6 address<\/li>\n\n\n\n<li>CNAME record \u2013 points a domain to another domain<\/li>\n\n\n\n<li>MX record \u2013 defines mail servers for a domain<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Practical_use_cases\"><\/span>Practical use cases<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">DNS is used for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>opening websites using domain names<\/li>\n\n\n\n<li>directing traffic to hosting servers<\/li>\n\n\n\n<li>configuring email delivery systems<\/li>\n\n\n\n<li>managing subdomains and services<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Practical_implications\"><\/span>Practical implications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">DNS changes (such as updating records or changing nameservers) are not instant. They require propagation across global DNS servers, which can take time depending on caching and provider configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During propagation, some users may see the old version of a service while others already see the updated one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Security_considerations\"><\/span>Security considerations<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">DNS itself does not encrypt data. Because of this, additional technologies such as DNSSEC or encrypted DNS protocols can be used to improve integrity and security.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DNS is also a target for abuse, such as DNS tunneling, where the system is misused to transmit hidden data through DNS queries.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Summary\"><\/span>Summary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">DNS is a core internet protocol that translates domain names into IP addresses.
